EU Citizens and the UK State Pension Post-Brexit: What You Need to Know

Brexit fundamentally altered the social security coordination arrangements between the UK and the EU. For EU citizens who have worked and contributed to the UK National Insurance (NI) system, and for UK citizens who have worked in the EU, the question of how those contributions count towards the UK State Pension — and how the two systems interact — has become significantly more complex.

This guide sets out the current position, the critical distinction between those covered by the Withdrawal Agreement and those whose contributions are governed by the Trade and Cooperation Agreement, and the practical options for maximising UK State Pension entitlement.

The UK State Pension: How Entitlement Works

The New State Pension (NSP), introduced in April 2016, is based solely on the individual's UK National Insurance record. To receive the full NSP (£241.30 per week in 2026/27), you need 35 qualifying years of NI contributions. To receive any State Pension at all, you need a minimum of 10 qualifying years.

Qualifying years are built through:

• Employed NI contributions (Class 1) from UK employment
• Self-employed contributions (Class 2 or Class 4) on UK self-employment profits
• Voluntary contributions (Class 2 or Class 3) paid by individuals not otherwise contributing
• NI credits, awarded in certain circumstances (caring responsibilities, unemployment, illness)

A qualifying year requires contributions (or credits) above a minimum earnings threshold for 52 weeks — not necessarily 52 actual weeks of work.

The Withdrawal Agreement: Protecting Pre-Brexit Rights

The UK-EU Withdrawal Agreement, which governs the rights of EU citizens in the UK and UK citizens in the EU as of 31 December 2020 (the end of the transition period), contains specific protections for social security coordination.

The key protections for EU citizens who were residing or working in the UK on or before 31 December 2020 and covered by the Withdrawal Agreement:

• Aggregation of periods: UK NI contribution periods and EU social security contribution periods can continue to be aggregated for the purpose of determining entitlement to the UK State Pension. An Italian national who worked in the UK for 12 years and then Italy for 15 years, and who was covered by the Withdrawal Agreement, can potentially count their Italian contributions to meet the UK's 10-year minimum threshold.

• Anti-discrimination: EU citizens covered by the WA must be treated the same as UK nationals for the purpose of social security.

• Uprating: State Pensions paid to EU citizens covered by the WA in EEA states and Switzerland should receive the annual "triple lock" uprating (the higher of CPI, earnings growth, or 2.5%).

Who is covered by the Withdrawal Agreement?: Broadly, EU citizens who were lawfully residing or working in the UK on 31 December 2020, and UK citizens lawfully residing in an EU member state on the same date. These individuals must have applied for (and been granted) Settled Status or Pre-Settled Status under the EU Settlement Scheme (UK side) or the equivalent national scheme in their EU country of residence.

The Trade and Cooperation Agreement: A Different Regime

The UK-EU Trade and Cooperation Agreement (TCA), which came into force on 1 January 2021, governs social security for individuals who began working across UK-EU borders after the transition period — i.e. those not covered by the Withdrawal Agreement.

The critical difference: The TCA does not include a general aggregation provision for State Pension purposes. This means that EU citizens who begin working in the UK after 31 December 2020 (and were not previously covered by the WA) cannot count their EU social security contribution years towards meeting the UK State Pension thresholds, and vice versa.

This is a significant change. Under the pre-Brexit coordination rules (based on EU Regulation 883/2004), contribution periods in all EEA states could be aggregated — meaning a person with contributions spread across multiple EU countries could combine them to reach the minimum thresholds. That coordination mechanism does not apply to new entrants to the UK from the EU after 2020.

What the TCA does provide:

• Anti-discrimination in respect of social security
• Coordination of certain social security benefits (in particular, export of some benefits)
• But not general aggregation for pension entitlement

Bilateral UK-EU Member State Treaties

Post-Brexit, the UK has concluded bilateral social security agreements with a number of individual EU member states, to partially replace the coordination that existed under EU regulations. As of mid-2026, bilateral agreements are in force with a small number of states, with negotiations ongoing with others.

These bilateral agreements vary in scope. Some provide for aggregation of contribution periods (which would help an EU citizen count home-country periods towards UK State Pension minimum thresholds); others do not. The specific position for your country of citizenship and current residence should be verified against the latest position on GOV.UK's international pension and social security pages.

Voluntary NI Contributions from Within the EU

For EU citizens and UK nationals who live in an EU country but want to maintain or build UK State Pension entitlement, the option to pay voluntary NI contributions from abroad is important.

Class 2 NI contributions (for individuals working abroad) cost approximately £3.45 per week (2026/27 rate) and count towards the State Pension at the same rate as standard employed contributions. This makes them exceptionally cost-effective: a full year of Class 2 NI costs approximately £179 and builds 1/35th of the full State Pension — equivalent to an annual pension income of approximately £359 per year, payable for life from State Pension age.

Class 3 NI contributions (for individuals not working) are more expensive — approximately £17.45 per week in 2026/27, around £907 per year — but still represent a worthwhile purchase for individuals with gaps in their record.

Eligibility for Class 2 from the EU: UK nationals living in an EU state can pay voluntary Class 2 NI contributions if they were previously employed or self-employed in the UK. EU citizens who have worked in the UK may also be eligible. The specific eligibility rules should be verified with HMRC's National Insurance section, and an application (Form CF83) is required before starting contributions.

Back-filling gaps: HMRC periodically allows taxpayers to pay contributions for gaps in their NI record going back further than the usual six-year window. The 2025 extension allowed back-filling to 2006 — the window has since closed, but future extensions are possible. Monitoring this and acting promptly if a window opens is important for maximising State Pension.

Checking and Projecting Your State Pension

All UK taxpayers (including non-residents) can check their NI record and obtain a State Pension forecast through the Check Your State Pension service on GOV.UK, using their Government Gateway login. This shows:

• Total qualifying years to date
• Years when contributions were credited
• Gaps in the record
• Projected State Pension at State Pension age (currently 66, rising to 67 by 2028)

For EU citizens working in both the UK and an EU member state during a single tax year, the NI regulations (both pre- and post-Brexit) generally provide for contributions to be made in only one country at a time (the country of main employment or habitual residence). Dual NI contributions — paying in both the UK and an EU country simultaneously — are generally not required or permitted.

Frozen Pension Concern

A separate but related issue: the UK State Pension is frozen (not uprated) for individuals living in certain countries when they first claim. EEA countries (EU member states, Norway, Iceland, Liechtenstein) and Switzerland receive annual uprating under the Withdrawal Agreement (for WA-covered individuals) and, currently, under the TCA arrangements. However, for UK nationals living outside the WA/TCA framework — including those in countries without an uprating agreement — the pension can be frozen at the rate at the date of first claim or first departure from the UK, whichever is relevant.

How Global Investments Can Help

Navigating UK State Pension entitlement across borders — particularly in the post-Brexit environment — requires careful analysis of Withdrawal Agreement coverage, NI contribution history, and the available voluntary contribution options. At Global Investments, our advisers help EU and UK nationals understand their State Pension entitlement, assess whether voluntary NI top-ups are cost-effective, and integrate the State Pension into a broader retirement income plan.
